"""
STORM Wiki pipeline powered by Mistral-7B-Instruct-v0.2 hosted by VLLM server and You.com search engine.
You need to set up the following environment variables to run this script:
    - YDC_API_KEY: You.com API key
You also need to have a VLLM server running with the Mistral-7B-Instruct-v0.2 model. Specify `--url` and `--port` accordingly.

Output will be structured as below
args.output_dir/
    topic_name/  # topic_name will follow convention of underscore-connected topic name w/o space and slash
        conversation_log.json           # Log of information-seeking conversation
        raw_search_results.json         # Raw search results from search engine
        direct_gen_outline.txt          # Outline directly generated with LLM's parametric knowledge
        storm_gen_outline.txt           # Outline refined with collected information
        url_to_info.json                # Sources that are used in the final article
        storm_gen_article.txt           # Final article generated
        storm_gen_article_polished.txt  # Polished final article (if args.do_polish_article is True)
